You can configure your PIN code on this page.

Figure 3-12 PIN Management

 SIM Card Status: Shows the status of your SIM card.

 PIN Management: You can select whether to enable this function or not. Once the PIN

code function is enabled, every time you start the device with this SIM card inserted, you

need to enter the PIN code. But you can go to enable the auto-unlock PIN function, which

could save you this trouble.

 PIN: Personal Identification Number of the SIM card. It consists of 4-8 digits.

 PUK: PIN Unlocked Key. It consists of 8 digits.

 Remaining Attempts: Shows how many attempts are left for you to try entering the PIN or

PUK code. You have 3 attempts at most for entering the PIN code and 10 attempts at most

for entering the PUK code. If you accidentally fail in three attempts, the PIN will be locked

and you will be required to enter the PUK code that is written on your SIM card (as shown

in Figure 3-13).

 Auto-unlock PIN upon Power-on: When the PIN code is required upon device restarting,

it will be validated automatically once. If validation failed, you need to enter the PIN code

on the Status page.

If the current status of PIN is disabled, you can select Enable and set a PIN code, and then

click Apply to make your settings take effect. While, if the SIM card’s current status is PIN

enabled and verified, you can select Disable and enter the current PIN code, or select Modify

and set a new PIN code, and then click Apply to make your settings take effect.
